Publication number: 20170221220Abstract: A pixel of a distance sensor includes a photosensor that generates photocharges corresponding to light incident in a first direction. The photosensor includes a plurality of first layers having a cross-sectional area increasing along the first direction after a first depth and at least one transfer gate which receives a transfer control signal for transferring the photocharges to a floating diffusion node. A strong electric field is formed in the direction in which the photocharges move horizontally or vertically in the pixel, thereby accelerating the photocharges, allowing for increased sensitivity and demodulation contrast.Type: ApplicationFiled: April 19, 2017Publication date: August 3, 2017Inventors: Eric Fossum, Tae Yon Lee

Publication number: 20170221221Abstract: The present disclosure is a method to measure the distance between the place where the first image is acquired and the target distance after comparing and analyzing the image acquired through vision sensor with the established database. The database stores images of each section and image information by using the vision sensor. The distance measuring method analyzes the characteristics of the images transmitted by a user and the characteristics of the objects on images, compares them with the database, selects the image most similar to the corresponding image from the database, and calculates the distance to the user.Type: ApplicationFiled: February 6, 2015Publication date: August 3, 2017Inventors: Yong Wan PARK, Soo Jung HUR, Jin Seon SONG, Chang Hwan CHOI

Publication number: 20170221222Abstract: In accordance with the teachings described herein, systems and methods are provided for generating a seed plan for use in radiation therapy. The system includes an image database, the image database comprising image slices and a seed template database comprising seed templates. A contour engine is configured to generate target contour data to identify one or more objects within each image slice. A reslicer engine is configured to rotate the contoured image about an angle of rotation to produce a resliced contoured image, such that the resliced contoured image is resampled at an angle perpendicular to the angle of rotation and intersecting an isocenter. The system also includes a seed grid engine configured to generate a seed grid perpendicular to the angle of rotation.Type: ApplicationFiled: February 6, 2017Publication date: August 3, 2017Inventor: JONATHAN WILLIAM PIPER

Publication number: 20170221223Abstract: A method is described for obtaining a position of a main lens optical center of a plenoptic camera. The plenoptic camera has a micro-lens array (MLA) positioned in front of a sensor, the main lens optical center position being defined in a referential relative to the sensor. Such method is remarkable in that it obtains, from a 4D raw light-field data of a monochromatic scene, a set of symmetry axes, each symmetry axis of the set being defined as a line associated with a micro-image, the line passing in the neighborhood of the micro-image center coordinates of the micro-image it is associated with, and in the neighborhood of the brightest pixel in the micro-image it is associated with, the set comprising at least two symmetry axes and determines the position of the main lens optical center according to at least two symmetry axes of the set.Type: ApplicationFiled: January 26, 2017Publication date: August 3, 2017Inventors: Wei HU, Erik REINHARD, Mozhdeh SEIFI

Publication number: 20170221224Abstract: A storage device stores capturing conditions containing a viewpoint position and a shooting direction of the camera, model data containing a shape of a segmented mirror, and feature point data representing a positional relationship among a viewpoint position and feature points. A camera captures the segmented mirror having a reflective surface to obtain a captured image containing at least a part of the reflective surface. A marker object has feature points, and is fixed at a predetermined position with respect to the camera. A feature-point extracting unit extracts multiple feature points from a captured image when the feature points are reflected in the reflective surface, and determines positions of the feature points within the captured image. A position measuring unit calculates a position of the segmented mirror, based on the capturing conditions, the model data, the feature point data, and the positions of the feature points within the captured image.Type: ApplicationFiled: July 31, 2014Publication date: August 3, 2017Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Yukiyasu DOMAE, Makito SEKI, Shintaro WATANABE, Satoru SOFUKU, Yutaka EZAKI

Publication number: 20170221225Abstract: A method to correct for drift in an electronic device is described. The method comprises determining a first center pose of the electronic device; tracking, using a sensor in conjunction with computer vision operating on a processor, at least one key point within a scene when the first center pose is within a tolerance with respect to a reported center pose; determining a derived center poser based upon the first center pose and the at least one key point; disabling the sensor for a predetermined time; determining, after the predetermined time, whether a second center pose is within the tolerance with respect to the derived center pose; tracking, using the sensor, the at least one key point when the second center pose is within the tolerance with respect to the derived center pose; and adjusting the second center pose when there is a difference between the second center pose and the derived center pose.Type: ApplicationFiled: February 1, 2017Publication date: August 3, 2017Applicant: Samsung Electronics Co., Ltd.Inventor: Christopher A.
